Site description (2000 baseline)
A very large area of outer archipelago inside the Saaristomeri National Park: the site's boundaries have been drawn to include the most ornithologically important parts of the park. Large areas of open water dominate the landscape, although the numerous islands are also impressive. Most of the islands are small, stony and treeless with steep shores. Jurmo, the largest, is ornithologically the most diverse and important, supporting long stony or sandy ridges and large, open areas of treeless heath. Boating and other human activities are much scarcer than within the inner archipelago.

Key biodiversity
An exceptionally important breeding area for archipelagic avifauna, with total numbers exceeding 20,000 pairs. Also nationally important as a staging area for waterbirds.
